Title: Method of controlling voltage of inverter
Inventor: NOCHIDA NORIO
IPC: H02P27/06
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To contrive the improvement of accuracy in positioning and the avoidance of hunting in the vicinity of objective stop position, in the case of performing the stop position decision control of a load rotor main shaft. SOLUTION: This method specifies that the required compensated torque boost property line be the property line L1 being obtained by reducing the correction specified as ΔVd=Vs-α.f (α: proportional constant), in case of ΔVd=Vs-α.f<n> (Vd: inverter output voltage) n=1, from usual torque boost property, in low frequency range 0<=f<=f2 (f: output frequency) being designated, according to the dynamic characteristic of the load rotation system of an inverter.  This method enables the avoidance of the hunting of main shaft action in the vicinity of the objective stop position, by reducing the quantity of sudden change of external force added to the whole rotation system of the induction motor accompanying the inversion of polarity of the output voltage Vd of an inverter for the amount of torque boost in the case where the main shaft has overpassed the objective stop position, without substantially reducing the torque boost dive property of a load induction motor, by properly selecting the above constants Vs and f2 or α.

Title: Formation of resist pattern
Inventor: WATANABE HISASHI
IPC: H01L21/30
Filed: 1987-01-23
Abstract: PURPOSE:To prevent a resist from being charged with electricity by incident electrons by a method wherein one layer of film out of multilayered resist films formed on a substrate is composed of a conductive high-polymer thin film and these multilayered resist films are exposed to an electron beam. CONSTITUTION:A conductive high-polymer thin film 2, e.g., a thin film of polyvinyl alcohol doped with minute particles of carbon, is applied to the surface of a silicon substrate 1. Then, after this assembly has been heat-treated, it is coated with a silicone-related resist 3, e.g. chloromethylated polyphenylsiloxane. After this assembly has been heat-treated furthermore, a two-layer resist is formed. After that, after this assembly has been exposed by an electron beam and then developed, a silicone-related resist pattern is formed. Lastly, after the conductive high-polymer film 2 has been etched by a reactive ion etching method using a gas of O2, a pattern 5 of the conductive high-polymer thin film is formed. By this method, the exposure using the electron beam can be executed by excluding the situation that the assembly is charged with electricity by incident electrons. As a result, the electron beam is not bent, and it is possible to prevent the distortion of a pattern and the displacement of the pattern.

Title: Crack detecting device
Inventor: MARUTA NAOYUKI
IPC: G01N29/14
Filed: 1995-01-05
Abstract: PURPOSE: To detect the cracking of a work with accuracy. CONSTITUTION: First and second counters respectively obtain first and second count values A1 and B1 by counting the numbers of AE waves which are generated within a prescribed period of time and exceed first and second levels and a first dividing circuit 29 finds the ratio C1 (=A1 /B1 ) of the first count value A1 to the second count value B1 . Then a first comparator circuit 32 compares the ratio C1 with a reference value Y for crack and, when C1 >Y, discriminates that a work has cracked. Even though noise is generated when sludge is crushed, A1 /B1 >Y does not occur when the A1 /B1 is found from a signal based on the noise, because high-level and relatively low-level waves exist in a mixing state in the waveform of the noise and the number of waves contained in the first count value A1 is smaller than that of waves contained in the second count value B1 . Therefore, erroneous judgment can be prevented.
